This Vollrath EWTHV-0,5 is a used mixer and blender — sometimes referred to as a dissolver or high-speed disperser — designed for mixing, blending, and dispersing materials in laboratory or small-batch production environments. Vollrath is a recognised manufacturer of industrial mixing and processing equipment, serving laboratory, chemical, and process industries with a range of precision mixing solutions.
The machine is powered by a 0.30 kW electric motor rated for 218–242 volt single-phase or 380–420 volt three-phase supply, with a maximum speed of 1,375 rpm delivered through a variable speed drive, allowing the operator to adjust mixing intensity to suit the application. The unit is ATEX compatible, making it suitable for use in potentially explosive atmospheres, and the motor carries an Ex designation consistent with that certification — though buyers are advised to verify the ATEX status independently, as the seller notes this as a point to check.
The dissolver head accepts interchangeable dissolving discs in four diameters: 30, 50, 65, and 90 mm, providing flexibility for different vessel sizes and batch volumes. The clearance between the shaft and the frame is 200 mm. A mechanical lifting mechanism allows vertical adjustment of the head, with a maximum stroke of 250 mm, and a switch is fitted — both of these features are noted by the seller as requiring inspection. The machine is supplied without an agitator.
The footprint is compact at 0.55 × 0.45 m, with a total height of 0.95 m, making it well suited to bench or floor placement in a laboratory setting. The unit carries serial number 21.624, was manufactured in 1987, and is located in Barneveld, Netherlands.
